An animation of 2008 TC3's excited rotation prior to entering the atmosphere. The asteroid was discovered by Richard A. Kowalski at the Catalina Sky Survey (CSS) 1.5-meter telescope at Mount Lemmon, north of Tucson, Arizona, US, on October 6, 06:39 UTC, 19 hours before the impact.
An example list of near-Earth asteroids that passed more than 1 lunar distance (384,400 km or 0.00256 AU) from Earth in 2008. 2007 TU 24 (~250 meters in diameter) passed 1.44 LD (554,000 km) from Earth on January 29, 2008. 2008 CE 22 (~18 meters in diameter) passed between 0.9997 and 1.0023 LD (384,300 to 385,300 km) from Earth on February 6, 2008.
2008 TC3, the first asteroid detected before impacting Earth. Fragment has been named as Almahata Sitta meteorite. [71] In JPL as 1 kt. [15] 2008, Nov 20 [15]
On October 6, 2008, while observing with the CSS 1.5 meter (60") telescope at Mount Lemmon Observatory, he discovered 2008 TC 3. Approximately 20 hours after its discovery this asteroid entered the Earth's atmosphere over Sudan, becoming the first asteroid discovered before impact with the earth. [4] Kowalski was honored with a small piece of ...
On 7 October 2008, an approximately 4 meter asteroid labeled 2008 TC 3 was tracked for 20 hours as it approached Earth and as it fell through the atmosphere and impacted in Sudan. This was the first time an object was detected before it reached the atmosphere and hundreds of pieces of the meteorite were recovered from the Nubian Desert .
Notable for imaging the first meteor to be predicted to strike the Earth, 2008 TC3. [1] Launched 28 Aug 2002 by an Ariane V155 , this European Meteorology satellite is in a Geostationary orbit . While Meteosat 8 meteorological instruments are working, solid state power amplifier SSPA-C failed in October 2002.
The Dutch-American astronomer Peter Jenniskens in the Nubian Desert with a fragment of 2008 TC3, an asteroid observed by the WHT just days earlier. Astronomers use the WHT to conduct scientific research across most branches of observational astronomy, including Solar System science, galactic astronomy, extragalactic astronomy and cosmology ...
In 2008, Jenniskens, together with Muawia Shaddad, led a team from the University of Khartoum in Sudan that recovered fragments of asteroid 2008 TC3 in the Nubian Desert, marking the first time meteorite fragments had been found from an object that was previously tracked in outer space before hitting Earth.
